Obtaining Public IP Addresses
To send audio streams over the public internet you need to use a public IP address assigned to you
by your ISP (Internet Service Provider).
A public IP address is like your public telephone number and allows you to be contacted over the
internet in much the same way people dial your public telephone number. They come in two forms;
dynamic (DHCP) and static. Most ISPs assign a dynamic public IP address by default, which can
often change without you knowing. This is suitable for a quick demo of your Tieline codec, but for a
permanent installation you will need to request a permanent static public IP address.
Once the Static Public IP address is assigned to your internet connection (router) at the studio you
need to create a link between the public IP address and your codec's private IP address on the
LAN. This is called Network Address Translation.
Depending upon how your network is configured, it may also be possible to simply connect your
Tieline codec directly into your ADSL modem/router and receive a public address from the router.
Private LAN IP Addresses
By default your Tieline codec will normally be automatically assigned a private IP address when you
connect it to a typical router over a LAN.

Description
ISP's allocate a static public IP address to
allow network devices to communicate with
each other over the internet. It works like a
public telephone number and will allow your
remote codec to call your studio codec over
the Internet.
ISP's usually allocate
(automatically) assigned
addresses to allow network devices to
communicate with each other over the
Internet. (Not recommended for
installations because
connect to your ISP the IP address can
change).
A DHCP server-allocated IP address that is
automatically assigned to a device on a
LAN to allow it to communicate with other
devices and the internet. This address can
change each time a device connects.
A network administrator-allocated static
address which is programmed into a device
to allow it to connect to a LAN. Often a
security measure to only allow access to
devices approved
